Serial No. 544,791.

This invention relates to liquid cooling installations, and has for an object'to provide an organization having improvedmeans for controlling the fiow' of liquids during the cooling process. 1 I

The utility of the present invention is more particularly directed to the cooling of milk in dairies, but it is to be understood, that such utility is no limitation upon the invention, and thatthe device may be employed for cooling liquids of any kind for any purpose, and in any location.

A further object of the invention is to provide in a liquid cooling installation, improved guiding fins and'members for preventing the discharge of the llquid longitudinally beyond the ends of the cooling pipes over which itis conducted."

A further object of the invention is to provide a cooling organization employing two different refrigerating mediumswith 7 different pipes or coils of pipes for the different types of cooling mediums, and with different types of directing finsupon the different types of pipes.

I A further ob ect ofthe invention is t provide improved means for caring for the expansion and contraction of the cooling pipes incident upon the variations of temperature during, the refrigeration.

The invention, therefore, comprises anorganization which embodies a frame work upon which is mounted a trough or other means for discharging liquid to becooled, with underlyingvertical series of pipes, with centering fins along the bottom of each, the series being divided into two sections, the upper section being normally supplied with cold water, v frigerated gases so that the temperature of the overflowingliquid will be brought gradually from this ini low temperature at the discharge, the water coils or pipes being provided with end fit tings having inclined guiding extremities, and with improved types of spoon shaped fins upon the gas section.

Theinvention is directed to other'objects,

and possesses other features of novelty and tion with the housing or e before and subsequent to and the lowersection with retial temperature to a very advantage, some of which, together with the foregoing, will bev hereinafter more fully set forth.

Figure 2' is a view of one of the for supporting the pipe coils, Figurei3 is a fragmentary view partly in 69 elevation and. partly in section of the end fittings of the water coils, Figure l is a fragmentary view partly in elevationand partly in section of the end fittings of the gas coils, I Figure 5 is a view in elevation of one of the guiding fins applied 'to'one of the pipes, as indicated by arrow 5, at F igure i, and Figure 6 is a view of the spoon shaped stanchions fin, taken from the same directionas Fig- 7 ure 5,'but removedfrom the pipe. 1 I

Like characters of reference indicate corresponding parts throughout the several views. I I a '1 lhe present installation comprises 'stanchions 10 and 11 which are supported in any approved manner, as by the frame work 12. As shown at Figure 1,'the stanchion is di# vlded into sections vertically, but as shown at r Figure 2, the stanchion-is unitary. So far as 1 the present invention is'conce'rned, it is 1111-. material whether such stanchion be integral I or in sections.

ing centralizing fin 15. I

Beneath the conduit 14, the stanchions 1 0 and 11 will support two separate cooling units; indicated in their entirety as A and B, A being supplied with cold water,the I said unit having conduits 16 and 17 for conduit or trough for milkwith a depend- 9 if c l a 5 inlet andoutlet of such water, which'said conduits respectively, pass through openings 18 and 19 in stanchions 11.

This water cooling unit is provided at each end with fittings 20 in the form of return bends, the ends, however, being formed upon planes inclined to a normal vertical as indicated at 21 in Figures 1 and 3. These fittings 20 may be produced in any approved manner, but it is the present intent that they shall be cast integral, and.

therewith, trunnions 22, which trunnions 22 pass through openings 23 in the stanchion 11 and provide perforations 24, for the receipt of pins 25. j Between the opposed fittings 20, cooling pipes 26 are employed, and as usual, it is the intent that these cooling "pipes shall be constructed of relatively thin metal, and the attachment at the end fittings 20 will be made in any approved manner; At the present time, the practice indicates sweating these pipes into the fittings, but it is to b understood, thatother meansof connection is fully within the. scope of the present invention. i

Each'of the pipes 26 is provided along its longitudinal lower median line with a downwardlyextending fin 27. This fin is in accordance with the present day practice in such installations, and serves to centralize the drip of each pipe upon the underlying pipe' so that the fluid passing over the several pipes will cover the greatest possible area to fully employ the refrigerating properties of the fluid within the pipe.

The construction of fittings such .astliat shown at 20, does not seem .feasiblefor the gas section of the cooling coil. A fitting 28 is, therefore, employed for connecting the pipes of the gas section. These pipes correspond in general terms, to the pipes of the water cooling section, and have been given the like number of 26. They are also provided with fins 27 in like manner, and for the same purpose. The end fittings 28 are also provided with the same lugs 22 with the openings 24 to be inserted through the stanchions. Thelength of these lugs 22 is such that the pipes extending between the stanchions 10 and 11 are free to expand and contract according to the temperature, and

such expansion and'contraction is compensated for by the sliding actionof the lugs 22 in the perforations 23 of the stanchions.

The gas pipes 26 may be connected with the fittings 28 also in any approved manner,

but' preferably, these pipes 26 will be upon the exterior of the fittings as distinguished from being inserted into the fittings as is the case in the water unit, and may be fixed in any approved manner, but the present practice indicates the preferance of sweating the pipes upon the fitting.

For this type of unit, the pipes are provided with the fins C. These fins C comprise a strip of metal, either bent or diecut as occasion may make necessary, having a U-shaped recess 29 properly proportioned to fit the pipes 26 when located at an angle to the horizontal as shown particularly at Figure 4. These fins are dished or spooned as indicated at 30, so that when positioned as shown at Figures 1 and 4, the lower and outer extremity 31 extends well beyond the upper extremity 32 of the under! lying fin, providing for properly directing the flowing milk to prevent it escaping over the ends, of the pipes 26 onto the fittings.

Underlying the whole, is a trough 33 or receiving conduit of substantially the usual andordinary type. V The gas coil is, of course, provided with inlet and outlet connections 34 and 35; t is designed that the gaseous fluid will be of substantially the usual and ordinary nature, such for instance,

operation of thedevice would bemere sur plusage.

Of course, the liquid cooling installation,

herein illustrated,;may be modified invarious Ways without departing fromtheinvention herein set forth and hereinafter claimed.
